DETAILED DESCRIPTION

In the following detailed description, reference is made to the accompanying drawings, which form a part hereof. In the drawings, similar symbols typically identify similar components, unless context dictates otherwise. The illustrative embodiments described in the detailed description, drawings, and claims are not meant to be limiting. Other embodiments may be utilized, and other changes may be made, without departing from the spirit or scope of the subject matter presented here.

Referring generally to FIGS. 1 through 9, a system 100 for storing and utilizing a selected portion of nuclear reactor generated heat is described in accordance with the present disclosure. One or more energy transfer systems 104 may divert energy (e.g., thermal energy or electrical energy) from a portion of a nuclear reactor system 101, such as a nuclear reactor 102 or an energy conversion system 110, to one or more heat storage materials 116 of an auxiliary thermal reservoir 112. Then, in response to a shutdown event (e.g., scheduled shutdown or emergency shutdown) of the nuclear reactor system 101, a heat supply system 114 may supply a portion of the thermal energy stored in the one or more auxiliary thermal reservoirs 112 to at least one energy conversion system 110 of the nuclear reactor system 101. The electrical energy produced by the energy conversion system 110 may then be supplied to an external load 118 (e.g., external power grid) or an internal load (e.g., an operation system of the nuclear reactor system 120).

In embodiments illustrated in FIG. 2A, the nuclear reactor 102 of the nuclear reactor system 101 may include, but is not limited to, a thermal spectrum nuclear reactor, a fast spectrum nuclear reactor, a multi-spectrum nuclear reactor, a breeder nuclear reactor, or a traveling wave reactor. For example, the energy produced by a thermal spectrum nuclear reactor may be diverted from the thermal spectrum nuclear reactor to an auxiliary thermal reservoir 112 using an energy transfer system 104. Then, in response to a shutdown event of the thermal spectrum nuclear reactor of a nuclear reactor system 101, a heat supply system 114 may supply a portion of the thermal energy stored in the auxiliary reservoir 112 to at least one energy conversion system 110 of the thermal spectrum nuclear reactor system 101. By way of further example, the energy produced by a traveling wave nuclear reactor may be diverted from the traveling wave nuclear reactor to an auxiliary thermal reservoir 112 using an energy transfer system 104. Then, in response to a shutdown event of the traveling wave nuclear reactor of the nuclear reactor system 101, a heat supply system 114 may supply a portion of the thermal energy stored in the auxiliary reservoir 112 to at least one energy conversion system 110 of the traveling wave nuclear reactor system 101.

The nuclear reactor 102 may include a nuclear reactor having a liquid coolant. For example, the liquid coolant of the nuclear reactor 102 may include, but is not limited to, a liquid metal salt coolant (e.g., lithium fluoride, beryllium fluoride or other fluoride salts), a liquid metal coolant (e.g., sodium, lead, or lead bismuth), a liquid organic coolant (e.g., diphenyl with diphenyl oxide), or a liquid water coolant. For instance, the energy transfer system 104 may divert energy from a portion of a liquid sodium cooled nuclear reactor of a nuclear reactor system 101 to an auxiliary thermal reservoir 112. In another instance, the energy transfer system 104 may divert energy from a portion of a liquid water cooled nuclear reactor of a nuclear reactor system 101 to an auxiliary thermal reservoir 112. In an additional instance, the energy transfer system 104 may divert energy from a portion of a lithium fluoride cooled nuclear reactor of a nuclear reactor system 101 to an auxiliary thermal reservoir 112. Then, in response to a shutdown event of the nuclear reactor system 101 a heat supply system 114 may supply a portion of the thermal energy stored in the auxiliary thermal reservoir 112 to at least one energy conversion systems 110 of the nuclear reactor system 101.

In an additional embodiment, the nuclear reactor 102 may include a nuclear reactor having a pressurized gas coolant. For example, the pressurized gas coolant may include, but is not limited to, pressurized helium gas or pressurized carbon dioxide gas. For instance, the energy transfer system 104 may divert energy from a portion of a pressurized helium cooled nuclear reactor of a nuclear reactor system 101 to an auxiliary thermal reservoir 112. Then, in response to a shutdown event of the nuclear reactor system 101 a heat supply system 114 may supply a portion of the thermal energy stored in the auxiliary thermal reservoir 112 to at least one energy conversion systems 110 of the nuclear reactor system 101.

In another embodiment, the nuclear reactor 102 may include a nuclear reactor having a mixed phase coolant. For example, the mixed phase coolant may include, but is not limited to, a gas-liquid mixed phase material (e.g., steam water-liquid water). For instance, the energy transfer system 104 may divert energy from a portion of a steam water-liquid water cooled nuclear reactor of a nuclear reactor system 101 to an auxiliary thermal reservoir 112. Then, in response to a shutdown event of the nuclear reactor system 101 a heat supply system 114 may supply a portion of the thermal energy stored in the auxiliary thermal reservoir 112 to at least one energy conversion systems 110 of the nuclear reactor system 101.

In additional embodiments illustrated in FIG. 3, the energy conversion system 110 may include, but is not limited to, a primary energy conversion system 302, an auxiliary energy conversion system 304, or an emergency energy conversion system 306. For example, in response to a shutdown event of the nuclear reactor system 101, a heat supply system 114 may supply a portion of the thermal energy stored in the heat storage material 116 of the auxiliary thermal reservoir 112 to at least one primary energy conversion system 302 of the nuclear reactor system 101. For instance, the primary energy conversion system 302 may include a turbine coupled to an electric generator used to supply electrical power to the primary load 118 (e.g., electrical power grid) of the nuclear reactor system 101. By way of an additional example, in response to a shutdown event of the nuclear reactor system 101, a heat supply system 114 may supply a portion of the thermal energy stored in the heat storage material 116 of the auxiliary thermal reservoir 112 to at least one auxiliary energy conversion system 304 of the nuclear reactor system 101. For instance, the auxiliary energy conversion system 304 may include an energy conversion system that supplements or replaces the output of the primary energy conversion cycle 302. For example, the auxiliary energy conversion system 304 may include a turbine coupled to an electric generator used to provide supplemental or backup electric power to the primary load 118 of the nuclear reactor system 101.

By way of a further example, in response to a shutdown event of the nuclear reactor system 101, a heat supply system 114 may supply a portion of the thermal energy stored in the heat storage material 116 of the auxiliary thermal reservoir 112 to at least one emergency energy conversion system 306 of the nuclear reactor system 101. For instance, the emergency energy conversion system may include a turbine coupled to an electric generator used to supply electric power to an operation system 120 (e.g., monitoring system, safety system, control system, coolant system or security system) of the nuclear reactor system 101. It will be appreciated by those skilled in the art that the emergency energy conversion system 306 may be configured to operate at temperatures lower than the operational temperature of the primary energy conversion system 302, allowing the emergency energy conversion system 306 to supply electrical energy to various operation systems 120 of the nuclear reactor system 101 in emergency situations where grid power is unavailable.

In a further embodiment, the energy conversion system 110 may include, but is not limited to, a turbine of the nuclear reactor system 101. For example, in response to a shutdown event of the nuclear reactor system 101, a heat supply system 114 may supply a portion of the thermal energy stored in the heat storage material 116 of the auxiliary thermal reservoir 112 to at least one turbine of the nuclear reactor system 101. By way of further example, in response to a shutdown event of the nuclear reactor system 101, a heat supply system 114 may supply a portion of the thermal energy stored in the heat storage material 116 of the auxiliary thermal reservoir 112 to a working fluid of at least one turbine of the nuclear reactor system 101. For instance, the heat supply system 114 may supply a portion of the thermal energy stored in the heat storage material 116 of the auxiliary thermal reservoir 112 to a pressurized steam working fluid of at least one turbine of the nuclear reactor system 101. It will be appreciated by those skilled in the art that the thermal energy supplied from the auxiliary thermal reservoir 112, via the heat supply system 114, to the working fluid of the turbine of the nuclear reactor system 101 may be used to augment the thermal energy supplied to the working fluid of the turbine from the nuclear reactor 102 of the nuclear reactor system.

In another embodiment, the energy conversion system 110 may include, but is not limited to, a topping cycle of the nuclear reactor system 101, a bottoming cycle of the nuclear reactor system 101 or a low grade heat dump of the nuclear reactor system 101. For example, in response to a shutdown event of the nuclear reactor system 101, a heat supply system 114 may supply a portion of the thermal energy stored in the heat storage material 116 of the auxiliary thermal reservoir 112 to at least one topping cycle of the nuclear reactor system 101. By way of another example, in response to a shutdown event of the nuclear reactor system 101, a heat supply system 114 may supply a portion of the thermal energy stored in the heat storage material 116 of the auxiliary thermal reservoir 112 to at least one bottoming cycle of the nuclear reactor system 101. By way of further example, in response to a shutdown event of the nuclear reactor system 101, a heat supply system 114 may supply a portion of the thermal energy stored in the heat storage material 116 of the auxiliary thermal reservoir 112 to at least one low grade heat dump of the nuclear reactor system 101.

In a further embodiment, in response to a shutdown event of the nuclear reactor system 101, a heat supply system 114 may supply a portion of the thermal energy stored in the heat storage material 116 of the auxiliary reservoir 112 to a boiling loop 322 of the nuclear reactor system 110, wherein the boiling loop 322 of the nuclear reactor system is in thermal communication with an energy conversion system 110 of the nuclear reactor system 101. For example, in response to a shutdown event of the nuclear reactor system 101, a heat supply system 114 may supply a portion of the thermal energy stored in the heat storage material 116 of the auxiliary reservoir 112 to a boiling loop 322 in thermal communication with a turbine of the nuclear reactor system. By way of further example, the boiling loop 322 may be in thermal communication with a topping cycle, a bottoming cycle or a low grade heat dump of the nuclear reactor system 101. It will be appreciated by those skilled in the art that the thermal energy supplied to the boiling loop 322 of the nuclear reactor system 101 from the auxiliary thermal reservoir 112 may be used to augment the thermal energy supplied to the boiling loop from the nuclear reactor 102 of the nuclear reactor system 101.

In embodiments illustrated in FIG. 4A, the energy transfer system 104 may divert energy from a portion of the nuclear reactor system 101 to a liquid heat storage material of an auxiliary thermal reservoir 112. For example, the liquid heat storage material may include, but is not limited to, an organic liquid (e.g., diphenyl with diphenyl oxide), a liquid metal salt (e.g., lithium fluoride, beryllium fluoride or other fluoride salts), a liquid metal (e.g., sodium, lead, or lead bismuth), or liquid water. For instance, the energy transfer system 104 may divert energy from a portion of the nuclear reactor system 101 to a mass of liquid sodium. In another instance, the energy transfer system 104 may divert energy from a portion of the nuclear reactor system 101 to a mass of liquid water. Then, in response to a shutdown event of the nuclear reactor system 101 a heat supply system 114 may supply a portion of the thermal energy stored in the liquid heat storage material of the auxiliary thermal reservoir 112 to at least one energy conversion systems 110 of the nuclear reactor system 101.

In another embodiment, the energy transfer system 104 may divert energy from a portion of the nuclear reactor system 101 to a pressurized gas heat storage material of an auxiliary thermal reservoir 112. For example, the pressurized gas material suitable for heat storage may include, but is not limited to, pressurized helium gas or pressurized carbon dioxide gas. For instance, the energy transfer system 104 may divert energy from a portion of the nuclear reactor system 101 to a mass of pressurized helium. Then, in response to a shutdown event of the nuclear reactor system 101 a heat supply system 114 may supply a portion of the thermal energy stored in the pressurized gas material of the auxiliary thermal reservoir 112 to at least one energy conversion systems 110 of the nuclear reactor system 101.

In additional embodiment, the energy transfer system 104 may divert energy from a portion of the nuclear reactor system 101 to a solid heat storage material of an auxiliary thermal reservoir 112. In one aspect, the solid heat storage material may include a continuous solid material forming a solid object. For example, the solid object suitable for heat storage may include, but is not limited to, a three dimensional monolithic object (e.g., a brick), a three dimensional porous object (e.g., a brick containing pores suitable for fluid flow), a three dimensional channeled object (e.g. a brick containing channels suitable for fluid flow), or a three dimensional engineered object (e.g., an object containing an engineered honeycomb pattern for increased heat transfer). For instance, the energy transfer system 104 may divert energy from a portion of the nuclear reactor system 101 to one or more solid monolithic objects, such as a brick, a rod, or a sheet of material. In another instance, the energy transfer system 104 may divert energy from a portion of the nuclear reactor system 101 to a solid engineered object, such as an object constructed of a high heat capacity honeycomb structured material. Further, the solid object may include, but is not limited to a ceramic solid object, such as a carbide ceramic (e.g., titanium carbide or silicon carbide) or a boride ceramic, a metal solid (e.g., iron or steel) object, or an environmentally present solid (e.g., rock or stone) object. For example, the energy transfer system 104 may divert energy from a portion of the nuclear reactor system 101 to a ceramic solid object. By way of further example, the energy transfer system 104 may divert energy from a portion of the nuclear reactor system 101 to an environmentally preexisting rock or stone structure located in close proximity to the nuclear reactor system 101.

In another aspect, the solid heat storage material may include a particulate solid material. For example, the particulate solid material may include, but is not limited to, a granular material (e.g. sand) or a powder material. For example, the energy transfer system 104 may divert energy from a portion of the nuclear reactor system 101 to a mass of sand. Further, the energy transfer system 104 may divert energy from a portion of the nuclear reactor system 101 to a mass of sand via heat pipes, wherein one portion of the heat pipes is in thermal communication with a portion of the nuclear reactor 102 and a second portion of the heat pipes is embedded in the volume of the sand. It will be recognized by those skilled in the art that the volume of the sand, and like solid materials, need not be constrained by the volume of a reservoir containment system 122, in that uncontained sand, stone, and like heat trapping materials surrounding a nuclear reactor system 101 may serve as a suitable heat storage material 116. Then, in response to a shutdown event of the nuclear reactor system 101 a heat supply system 114 may supply a portion of the thermal energy stored in the solid heat storage material of the auxiliary thermal reservoir 112 to at least one energy conversion systems 110 of the nuclear reactor system 101.

In a further embodiment, the energy transfer system 104 may divert energy from a portion of the nuclear reactor system 101 to a mixed phase heat storage material of the auxiliary thermal reservoir 112. For example, the mixed phase material suitable for heat storage may include, but is not limited to a gas-liquid mixed phase material (e.g., steam water-liquid water) or a liquid-solid mixed phase material (e.g. liquid sodium-solid sodium). For instance, the energy transfer system 104 may divert energy from a portion of the nuclear reactor system 101 to a mass of steam water-liquid water. Then, in response to a shutdown event of the nuclear reactor system 101, a heat supply system 114 may supply a portion of the thermal energy stored in the mixed phase heat storage material of the auxiliary thermal reservoir 112 to an energy conversion system 110 of the nuclear reactor system 101.

In another embodiment, the energy transfer system 104 may divert energy from a portion of the nuclear reactor system 101 to a mass of a heat storage material having a phase transition within the operating temperature of the auxiliary thermal reservoir 112. For example, an auxiliary thermal reservoir 112 having a heat storage material 116 with a phase transition at approximately 100° C. may continuously operate at temperatures above and below the phase transition at 100° C. Those skilled in the art will recognize that this allows the heat supply system 114 to supply thermal energy from the auxiliary reservoir 112 to the energy conversion system 110 of the nuclear reactor system 101 at reservoir temperatures above, below and at the phase transition temperature of the heat storage material 116. For instance, given that sodium has an approximate melting temperature of 97.7° C., a sodium based auxiliary reservoir 112 may operate in the liquid phase at temperatures above 97.7° C. and in the solid phase at temperatures below 97.7° C. Then, in response to a shutdown event of the nuclear reactor system 101, a heat supply system 114 may supply a portion of the thermal energy stored in the heat storage material 116 having a phase transition within the operating temperature of the auxiliary reservoir 112 to an energy conversion system 110 of the nuclear reactor system 101.

In another embodiment, the energy transfer system 104 may divert energy from a portion of the nuclear reactor system 101 to a mass of a heat storage material 116 contained in a reservoir containment system. For example, the reservoir containment system may include, but is not limited to, an external vessel or an external pool. By way of further example, the external vessel may include, but is not limited to an external liquid vessel or an external high pressure gas vessel. For instance, the energy transfer system 104 may divert energy from a portion of the nuclear reactor system 101 to a mass of liquid metal (e.g. liquid sodium) contained in an external liquid vessel. In another instance, the energy transfer system 104 may divert energy from a portion of the nuclear reactor system 101 to a mass of pressurized gas (e.g. pressurized helium) contained in an external high pressure vessel. By way of further example, the external pool may include, but is not limited to, a liquid pool. For instance, the energy transfer system 104 may divert energy from a portion of the nuclear reactor system 101 to a mass of liquid metal (e.g. liquid sodium) contained in an external liquid pool. Then, in response to a shutdown event of the nuclear reactor system 101, a heat supply system 114 may supply a portion of the thermal energy stored in the heat storage material 116 contained in the reservoir containment system to an energy conversion system 110 of the nuclear reactor system 101.

In another embodiment, the auxiliary thermal reservoir 112 may store the energy diverted from a portion of the nuclear reactor system 101 in the form of a temperature change in the heat storage material 116 of the auxiliary thermal reservoir 112. For example, the energy diverted from the nuclear reactor system 101 to the heat storage material 116 of the auxiliary thermal reservoir 112 may cause the temperature of the heat storage material 116 to increase. For instance, the energy diverted from the nuclear reactor system 101 to the heat storage material 116 of the auxiliary thermal reservoir 112 may cause the temperature of the heat storage material 116, such as a liquid metal 408 (e.g., liquid sodium), to increase from an initial temperature of approximately 100° C. to a temperature of approximately 500° C. Then, in response to a shutdown event of the nuclear reactor system 101, a heat supply system 114 may supply a portion of the thermal energy stored in the heat storage material 116 as a temperature increase to an energy conversion system 110 of the nuclear reactor system 101.

In another embodiment, the auxiliary thermal reservoir 112 may store the energy diverted from a portion of the nuclear reactor system 101 in the form of a phase change in the heat storage material 116 of the auxiliary thermal reservoir 112. For example, the phase change in the heat storage material 116 may comprise a solid-liquid phase change or a liquid-gas phase change. In one aspect, the energy diverted from the nuclear reactor system 101 to a solid heat storage material of the auxiliary thermal reservoir 112 may be stored in the heat storage material 116 by melting the heat storage material 116. For instance, the energy diverted from the nuclear reactor system 101 to a mass of solid sodium may liquefy the mass of sodium via a melting transition at approximately 97.7° C., thus storing a portion of the diverted energy in the liquid phase of the mass of sodium. It will be appreciated by those skilled in the art that the energy required to transform the heat storage material 116 from one phase (e.g. solid) to a new phase (e.g., liquid) is the heat of transformation (i.e., the “latent heat”). Then, in response to a shutdown event of the nuclear reactor system 101, a heat supply system 114 may supply a portion of the heat of transformation stored as thermal energy in the heat storage material 116 to an energy conversion system 110 of the nuclear reactor system 101.

In a further embodiment, as illustrated in FIG. 4B, the operational status of the auxiliary thermal reservoir may be monitored using one or more reservoir monitoring systems. For example, the reservoir monitoring system may include a temperature monitoring system, a pressure monitoring system, a system for determining the amount of energy stored in the thermal reservoir or a system for determining the amount of available energy capacity of the thermal reservoir. For instance, a system for determining the amount of energy stored in the thermal reservoir may include thermal and pressure monitoring devices combined with a computer system for applying an established algorithm (e.g., established equation-of-state for the storage material in question) relating temperature and pressure to the internal energy of the reservoir storage material (e.g., liquid metal or pressurized gas).

In another embodiment, the temperature of the auxiliary thermal reservoir 112 may be controlled using a reservoir temperature control system. For example, the reservoir temperature control system may be used to increase or decrease the temperature of the auxiliary thermal reservoir 112. For instance, in situations where the internal temperature of the auxiliary thermal reservoir reaches levels outside the predefined operational limits, the reservoir temperature control system may signal the heat supply system 114 to transfer a portion of the thermal energy stored in the auxiliary thermal reservoir 112 to an energy conversion system 110 of the nuclear reactor system 101.

In an additional embodiment, illustrated in FIG. 5A, the energy transfer system 104 may include, but is not limited to, an energy transfer system suitable for diverting thermal energy 106 from a portion of the nuclear reactor system 101 to the auxiliary thermal reservoir 112. For example, the energy transfer system suitable for diverting thermal energy 106 from a portion (e.g., primary coolant system) of the nuclear reactor system 101 to the auxiliary thermal reservoir 112 may transfer thermal energy from a portion of the nuclear reactor system 101 to the auxiliary thermal reservoir 112. Then, in response to a shutdown event of the nuclear reactor system 101, a heat supply system 114 may supply a portion of the thermal energy stored in the one or more auxiliary thermal reservoirs 112 to at least one energy conversion system 110 of the nuclear reactor system 101.

In a further embodiment, shown in FIG. 5A, the energy transfer system suitable for diverting thermal energy 106 from a portion of the nuclear reactor system 101 to the auxiliary thermal reservoir 112 may include, but is not limited to, a heat transfer system 504. For example, the heat transfer system 504 may transfer thermal energy from a portion of the nuclear reactor system 101 to the auxiliary thermal reservoir 112. For instance, the heat transfer system 504 may transfer thermal energy from a portion of the nuclear reactor system 101 to the auxiliary thermal reservoir 112 via thermal convection (e.g., natural convection or forced convection via coolant pump(s)). In another instance, the heat transfer system 504 may transfer thermal energy from a portion of the nuclear reactor system 101 to the auxiliary thermal reservoir 112 via thermal conduction (e.g., using a heat exchanger). Those having skill in the art will recognize that the heat transfer system 504 may be configured to transfer thermal energy from a portion of the nuclear reactor system 101 to the auxiliary thermal reservoir 112 using both thermal conduction and thermal convection. Then, in response to a shutdown event of the nuclear reactor system 101, a heat supply system 114 may supply a portion of the thermal energy stored in the one or more auxiliary thermal reservoirs 112 to at least one energy conversion system 110 of the nuclear reactor system 101.

In a further embodiment, the heat transfer system 504 may include, but is not limited to, a direct fluid exchange heat transfer system. For example, the direct fluid exchange heat transfer system may transfer thermal energy from a portion of the nuclear reactor system 101 to the auxiliary thermal reservoir 112. The direct fluid exchange heat transfer system may comprise a system for intermixing the coolant of the nuclear reactor 102 with the fluidic heat storage material 116 contained in the reservoir containment system 122. For instance, a fluid carrying loop may couple the primary coolant system of the nuclear reactor system 101 and the reservoir fluid containment system 122, allowing for the intermixing of the two fluids. The rate of reactor coolant-reservoir fluid intermixing may be controlled by the direct fluid exchange transfer system.

For example, excess energy from an energy conversion system 110 may be used to provide supplemental energy to the auxiliary thermal reservoir 112. For instance, when grid requirements are such that the energy conversion system 110 is producing excess electrical power, the excess power may be converted to thermal energy via an electrical-to-thermal energy conversion process (e.g., heating coil) and transferred to the auxiliary thermal reservoir 112, thus supplementing the energy transferred to the auxiliary thermal reservoir 112 via the energy transfer system 104 during normal operation.

In an additional embodiment, the energy transfer system 104 may include, but is not limited to, an energy transfer system suitable for establishing thermal communication between the nuclear reactor system and the auxiliary thermal reservoir. For example, in response to a condition, the energy transfer system suitable for establishing thermal communication between the nuclear reactor system and the auxiliary thermal reservoir may establish a thermal pathway between a portion of the nuclear reactor 102 (e.g., primary coolant system) and the auxiliary thermal reservoir 112. For instance, in the case of a direct fluid exchange heat transfer system, a control valve may be used to initiate the intermixing of the reactor coolant and reservoir fluid. In another instance, in the case of the heat transfer system employing a reactor-reservoir heat exchanger 514, a control valve may be used to initiate reactor coolant flow through the heat exchanger.

In an additional embodiment, the energy transfer system 104 may include, but is not limited to, an energy transfer system responsive to the determination of the amount of energy stored in the auxiliary thermal reservoir.

For instance, in the event the turbine-generator system is producing electrical power in excess of grid demand, the energy transfer system 104 may transfer energy (e.g., thermal or electrical) energy from a portion of the nuclear reactor system to an auxiliary thermal reservoir 112. Further, the energy transfer system 104 may include an energy transfer system suitable for diverting a specified percentage of the energy output of a nuclear reactor system to an auxiliary thermal reservoir. For example, a control system or operator may choose to transfer a pre-selected percentage of the nuclear reactor system 101 output and transfer at least a portion of that energy to the auxiliary thermal reservoir 112. It will be recognized by those skilled in the art that the level of energy output pre-selected to be transferred to the auxiliary thermal reservoir may be a function of time and may be derived from historic external power demand curves. For example, in times of day or times of year historically displaying relatively low grid demand, the control system or operator may choose to divert a larger percentage of the overall nuclear reactor system 101 output to the auxiliary thermal reservoir than the percentage transferred during periods of higher demand.

Further, the heat supply system suitable for supplying a specified portion of the energy stored in the auxiliary thermal reservoir to the energy conversion system may include a heat supply system suitable for supplying a specified percentage of the energy stored in the thermal reservoir to the energy conversion system. For example, the heat supply system suitable for supply a specified percentage of the energy stored in the thermal reservoir to the energy conversion system may be utilized to by a control system or operator to transfer a chosen percentage (e.g., 50% of the stored energy) of the energy stored in the auxiliary thermal reservoir 112 to an energy conversion system 110 of the nuclear reactor system 101.

Those having skill in the art will recognize that the state of the art has progressed to the point where there is little distinction left between hardware, software, and/or firmware implementations of aspects of systems; the use of hardware, software, and/or firmware is generally (but not always, in that in certain contexts the choice between hardware and software can become significant) a design choice representing cost vs. efficiency tradeoffs. Those having skill in the art will appreciate that there are various vehicles by which processes and/or systems and/or other technologies described herein can be effected (e.g., hardware, software, and/or firmware), and that the preferred vehicle will vary with the context in which the processes and/or systems and/or other technologies are deployed. For example, if an implementer determines that speed and accuracy are paramount, the implementer may opt for a mainly hardware and/or firmware vehicle; alternatively, if flexibility is paramount, the implementer may opt for a mainly software implementation; or, yet again alternatively, the implementer may opt for some combination of hardware, software, and/or firmware. Hence, there are several possible vehicles by which the processes and/or devices and/or other technologies described herein may be effected, none of which is inherently superior to the other in that any vehicle to be utilized is a choice dependent upon the context in which the vehicle will be deployed and the specific concerns (e.g., speed, flexibility, or predictability) of the implementer, any of which may vary. Those skilled in the art will recognize that optical aspects of implementations will typically employ optically-oriented hardware, software, and or firmware.

Consequently, as used herein, the specific exemplars set forth and the accompanying discussion are intended to be representative of their more general classes. In general, use of any specific exemplar is intended to be representative of its class, and the non-inclusion of specific components (e.g., operations), devices, and objects should not be taken limiting.

Those skilled in the art will appreciate that, in general, the same may be said of “sender” and/or other entity-oriented terms as such terms are used herein unless context dictates otherwise.

With respect to the use of substantially any plural and/or singular terms herein, those having skill in the art can translate from the plural to the singular and/or from the singular to the plural as is appropriate to the context and/or application.

The herein described subject matter sometimes illustrates different components contained within, or connected with, different other components. It is to be understood that such depicted architectures are merely exemplary, and that in fact many other architectures may be implemented which achieve the same functionality. In a conceptual sense, any arrangement of components to achieve the same functionality is effectively “associated” such that the desired functionality is achieved. Hence, any two components herein combined to achieve a particular functionality can be seen as “associated with” each other such that the desired functionality is achieved, irrespective of architectures or intermedial components. Likewise, any two components so associated can also be viewed as being “operably connected”, or “operably coupled,” to each other to achieve the desired functionality, and any two components capable of being so associated can also be viewed as being “operably couplable,” to each other to achieve the desired functionality. Specific examples of operably couplable include but are not limited to physically mateable and/or physically interacting components, and/or wirelessly interactable, and/or wirelessly interacting components, and/or logically interacting, and/or logically interactable components.

In some instances, one or more components may be referred to herein as “configured to,” “configurable to,” “operable/operative to,” “adapted/adaptable,” “able to,” “conformable/conformed to,” etc. Those skilled in the art will recognize that such terms (e.g., “configured to”) can generally encompass active-state components and/or inactive-state components and/or standby-state components, unless context requires otherwise.

While particular aspects of the present subject matter described herein have been shown and described, it will be apparent to those skilled in the art that, based upon the teachings herein, changes and modifications may be made without departing from the subject matter described herein and its broader aspects and, therefore, the appended claims are to encompass within their scope all such changes and modifications as are within the true spirit and scope of the subject matter described herein. It will be understood by those within the art that, in general, terms used herein, and especially in the appended claims (e.g., bodies of the appended claims) are generally intended as “open” terms (e.g., the term “including” should be interpreted as “including but not limited to,” the term “having” should be interpreted as “having at least,” the term “includes” should be interpreted as “includes but is not limited to,” etc.). It will be further understood by those within the art that if a specific number of an introduced claim recitation is intended, such an intent will be explicitly recited in the claim, and in the absence of such recitation no such intent is present. For example, as an aid to understanding, the following appended claims may contain usage of the introductory phrases “at least one” and “one or more” to introduce claim recitations. However, the use of such phrases should not be construed to imply that the introduction of a claim recitation by the indefinite articles “a” or “an” limits any particular claim containing such introduced claim recitation to claims containing only one such recitation, even when the same claim includes the introductory phrases “one or more” or “at least one” and indefinite articles such as “a” or “an” (e.g., “a” and/or “an” should typically be interpreted to mean “at least one” or “one or more”); the same holds true for the use of definite articles used to introduce claim recitations. In addition, even if a specific number of an introduced claim recitation is explicitly recited, those skilled in the art will recognize that such recitation should typically be interpreted to mean at least the recited number (e.g., the bare recitation of “two recitations,” without other modifiers, typically means at least two recitations, or two or more recitations). Furthermore, in those instances where a convention analogous to “at least one of A, B, and C, etc.” is used, in general such a construction is intended in the sense one having skill in the art would understand the convention (e.g., “a system having at least one of A, B, and C” would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and/or A, B, and C together, etc.). In those instances where a convention analogous to “at least one of A, B, or C, etc.” is used, in general such a construction is intended in the sense one having skill in the art would understand the convention (e.g., “a system having at least one of A, B, or C” would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and/or A, B, and C together, etc.). It will be further understood by those within the art that typically a disjunctive word and/or phrase presenting two or more alternative terms, whether in the description, claims, or drawings, should be understood to contemplate the possibilities of including one of the terms, either of the terms, or both terms unless context dictates otherwise. For example, the phrase “A or B” will be typically understood to include the possibilities of “A” or “B” or “A and B.

With respect to the appended claims, those skilled in the art will appreciate that recited operations therein may generally be performed in any order. Also, although various operational flows are presented in a sequence(s), it should be understood that the various operations may be performed in other orders than those which are illustrated, or may be performed concurrently. Examples of such alternate orderings may include overlapping, interleaved, interrupted, reordered, incremental, preparatory, supplemental, simultaneous, reverse, or other variant orderings, unless context dictates otherwise. Furthermore, terms like “responsive to,” “related to,” or other past-tense adjectives are generally not intended to exclude such variants, unless context dictates otherwise.
